Dropdown in combination with yes/no database

Hello all,

I have the following situation:

I have a thing called ‘Links’ in my database with four entries:

websites_enabled
books_enabled
example_enabled
example_enabled

They are all a yes or no entry in the database and can be changed by the user. Now I want to have those dynamic options in a dropdown list. So if a user has disabled websites, it will not show up but the other three options would. What would be the best way to do this?
